Solution - Linear equations with one unknown

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     2*d+18-(12-6*(d+7))=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (2d + 18) -  (12 -  6 • (d + 7))  = 0 

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   8d + 48  =   8 • (d + 6) 

Equation at the end of step  3  :

  8 • (d + 6)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    8   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 4.2      Solve  :    d+6 = 0 

 Subtract  6  from both sides of the equation : 
                      d = -6
